Goddard gravity model

(GGM, Goddard gravitational model)
(gravity model produced by Goddard Space Flight Center)

The term Goddard gravity model (or Goddard gravitational model) refers to models of gravity anomalies, termed gravity models or gravitational models or geopotential models) of various bodies developed by the Goddard Space Flight Center through data from space probes. These include successive versions of Goddard Lunar Gravity Models, Goddard Earth Gravity Models and Goddard Mars Gravity Models (Goddard Mars Models, or GMMs). One way of expressing them is using spherical harmonics coefficients.
